Description
This pin is used in conjunction with CFG_SEL0 to select
the power delivery profile of the device via an externally
connected RC circuit. Refer to Section 3.3, "Configuration
Selection (CFG_SEL0/CFG_SEL1)" for additional infor-
mation.
This pin is used in conjunction with VSEL1 to select the
correct source voltage from the DC-to-DC or AC-to-DC
solution. VSEL1 and VSEL0 select the voltage value from
the supported voltage capabilities in ascending order with
VSEL0 being the least significant bit (see examples
below).
For example, if an adapter supports 5, 9, and 20 V capa-
bilities, the VSEL1 and VSEL0 selections will be as fol-
lows:
VSEL1 VSEL0
0 0:
0 1:
1 0:
1 1:
5V
9V
20 V
RESERVED
In another example, if an adapter supports 5, 9, 12, and
20 V capabilities, the VSEL1 and VSEL0 selections will
be as follows:
VSEL1 VSEL0
0 0:
0 1:
1 0:
1 1:
5V
9V
12 V

For a mapping of the VSEL1/VSEL0 voltage assignments
for each CFG_SEL1/CFG_SEL0 configuration profile,
refer to TABLE 3-3: 32-SQFN CFG_SELx Configuration
Assignments on page 21.
Note: This function is only available in specific
device configurations.
This signal is used in conjunction with VSEL0 to select
the correct source voltage from the DC-to-DC or AC-to-
DC solution. VSEL0 and VSEL1 select the voltage value
from the supported voltage capabilities in ascending
order.
Refer to the VSEL0 definition for additional information.
Note: This function is only available in specific
device configurations.
